Neil,
Can you, please, spell check text in tutorial, my English is not well. Feel free to modify anything you don't like. If you use this tutorial as part of your web page add a link to texture tekstura117.psd.
I'm sending you one big crater I made in .psd format so you can look at it and perhaps figure out how it wes done. (I find my self in problems (English) when try to explain how I painted it, but I'll try.)

Thanks,

dodam
